Improvement of an X-ray imaging detector based on a scintillating guides screen

Development of a high-efficiency high-resolution imaging detector for 30–80keV X-rays

“…The scintillator presented here is an adaptation of a design used by Badel [8]. An array of pores is etched into a silicon wafer, which is opaque to visible light.…”

“…In this paper, we present the design and test of a first generation structured scintillator for a high-efficiency, high-resolution detector to work in the range above 30 keV using an alternative for producing light guiding screens by means of electrochemical etching [8,9]. For this initial work a pore pitch of 4 mm was chosen.…”

Improvement of the sensitivity and spatial resolution of pixelated CsI:Tl scintillator with reflective coating

“…Four methods for fabricating pixelated CsI(Tl) have been reported, namely a laser cutting method [3], scintillator-filled pores in a silicon matrix [4][5][6] and scintillator filling in an SU-8 mold [7]. Recently, a new deposition method for fabricating pixelated CsI(Tl) was introduced, which used patterned SU-8 photo resist (PR) on a glass substrate [8].…”

Pixel-Structured Scintillator with Polymeric Microstructures for X-Ray Image Sensors

“…Although substantial effort has been devoted to this new detector design, pixel-structured scintillators have only been realized on hard substrates, such as silicon wafers and SU-8 photoresistors [3], [4]. Flexible X-ray image sensors are very attractive [5] as they offer robustness and can be produced by a cost-effective fabrication process such as jet-printing [6].…”
